Xpages displaying differently on 2 servers

This is an odd one, but I may be missing something very simple.

We have 2 servers, both running 8.5.2 (call them A and B) which both hold a replica of a database. We have a very simple xpage which displays the richtext field (in read only mode) held in a document. If we edit/save the document on server A it displays correctly on that server using a browser, but it does not display correctly on server B. If we then edit/save the document on server B it displays correctly on that server but not on server A.

There is no form or document based security and when checking the field properties before and after the save/edit nothing changes (because it is the identical design - a replica).

There must be something behind the scenes which which Domino is changing but I can not work out what it is, and I can not find anybody who has had the same problem.

Any ideas?

Thanks and Happy New Year everybody.

Subject: Obvious - now that I posted the problem

The xpage decides which document to display based on the NoteID which is of course different on each server. Oops.
